The President had a headache on Monday evening and a brain scan showed that he had a bleeding under the skull bone, according to the statement from Sírio-Libanês Hospital in São Paulo. A decision was made to transport the 79-year-old approximately 100 miles from the capital Brasília.
The surgical procedure, which involved making one or more tiny perforations in the skull to drain the blood, is reported to have gone as planned without any complications.
Lula is stable, speaking as usual and can eat, says Dr. Roberto Kalil at a press conference according to Brazilian media.
He suffered no brain damage and there are no risks to his brain.
The President will remain under observation for a few more days and is expected to be able to return to Brasília next week, according to the doctors.
Lula da Silva was involved in a fall accident at home on October 19 and hit his head. He cancelled a planned trip to Russia where he was to participate in a Brics meeting. When he appeared shortly thereafter, he had a visible and swollen wound on the back of his head.
The bleeding was a consequence of the accident, according to the doctors.
